As said, bad control arms, tie rods, and ball joints will usually show up in uneven tire wear.
Jack up the front end. Insert the end of a crow bar in between the control arm bushing and the mount. Press on it like you are prying it, it does not need to be a hard push. Does it feel solid and does the rubber feel firm? Or is it squishy and does it feel like there is some "give". Do you see the pin and/or entire control arm moving when you press on the crow bar? If they are good, everything will be firm and there will be no movement when pressing on the bar.
To check the ball joints it helps to have a friend put the crow bar under the tire and like a lever, pull up and down against the tire. You watch the ball joint and see if the suspension is moving with the movement of the crowbar, or if the ball joint "gives" or allows the tire to move before the control arms move. There should be no vertical movement in the ball joint itself. You can also have your friend grab the top and bottom of the tire and wiggle it to see if there is lateral movement in the ball joint. There should be none, nor should he be able to move the tire like that.
For tie rods have your friend grab the front and rear of the tire and try to wiggle it left to right and back. Normal behavior is for the entire steering system to move with the wiggling. Watch the joints of the tie rods. If you see movement or slack inside the joint they are going. Really bad tie rods can show up as brake pulsation especially at high speeds.
